The lmdz model allows to output mass flux files that can be used as inversion model forcing files. This option is drive by the parameter <code>offline</code>

== option offline in LMDZ ==
To use this option you need :
* to put parameter <code>offline</code> to yes
* add the reference to <code><file_definition src="./file_def_phystoke_lmdz.xml"/></code> in <code>context_lmdz.xml</code>
* choose the output storage frequency with parameter <code>offline_time</code>. For example, for a storage all the 3hours (1day/8) we will choose <code>offline_time=8</code>
* if you are running with modipsl, modify lmdz.card to save mass flux files :

[OutputText]
List= (.... , wg.nc, tetag.nc, phig.nc, pbarvg.nc, pbarug.nc, masseg.nc)
[OutputFiles]
List= (.... ), \
(phystoke.nc, ${R_OUT_ATM_O_M}/${PREFIX}_1M_phystoke.nc, NONE)

* if you are not running with modipsl, save the output files : '''wg.nc''', '''tetag.nc''', '''phig.nc''', '''pbarvg.nc''', '''pbarug.nc''', '''masseg.nc''' and '''phystoke.nc'''
